Chris Lattner b818af539f now that ConvertTagDeclType is nice and simple, use it from UpdateCompletedType.

Chris Lattner 56096f3020 rename TypeHolderMap to TypeCache, which more aptly describes what it is.

Chris Lattner b1537ebdd4 rewrite some of the type refinement code to eliminate dangling pointers 
simplify the code and generally make it more robust.

Chris Lattner 86964a9653 Change the key of CGRecordLayouts from being an llvm type* to being a decl*. LLVM 
Type*'s can change as types are refined, so we can't use them as a stable key in
the map.  Decls don't change, so use them instead.

This patch was written by Anders, but he's too shy to commit it himself :)

Devang Patel e11664a0ef Rename classes and collections that maintain record layout information. 
Now, at AST level record info is maintained by ASTRecordLayout class.
Now, at code gen  level record info is maintained by CGRecordLayout class.

Devang Patel 75ef2f0b45 Take 2. 
Make target info available to clang code generator.  This is far from complete but this helps clang codegen module make progress.

At the moment target triplet and target description strings are hard coded in clang::TargetInfo
